Metra 71-049 adapters

These harnesses will allow you to plug your new speakers into the factory connectors present in the speaker openings for your vehicle. Two adapters are included for a pair of speakers.

Note: Some aftermarket speakers have terminals that are wider than this harness's slide-on connectors. You may need to widen the harness's female slide-on connectors, or use the slide terminals that may be included with the speakers. If you need to connect your new speaker's connectors to the Crutchfield harness, soldering is best. You can also crimp the wires if you prefer - see "Accessories."

Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if these adapters are compatible with your vehicle. Warranty: 60 days.

Note: Most vehicles will require additional installation parts  please identify your vehicle if you haven’t done so, then check here for a list of parts. You can also call an Advisor for more information.

Metra makes it simple

This adapters are quick and simple and save you from soldering or some other form of wire connecting and help keep stock appearance. Be warned if you are installing Rockford Fosgate speakers as they often have too large of clips and you will need to modify the adapter to work.

Clean, Quick and Easy

The speaker and stereo connections provided by Crutchfield for no cost, are obviously a better deal than paying $20.00 or more for the set elsewhere. They fit perfectly, and allow for a clean, quick and easy installation, and/or removal, without cutting into tiny wires inside a dashboard.

Worked Perfect in my 2004 Jeep GC Overland

These adapters make putting in a New speaker system fast and easy. No wire stripping and no crimping or cutting wires.. I would recommend if you plan on maybe selling your vehicle to replace the original equipment and use your new speakers in another vehicle.

Too easy!

They fit perfect. Just plug into existing truck plug and then plug on to speaker blades that match blade size (One small and one large for polarity. You can not screw this up. Just be carefull sliding blade connector on. Support the back on the speaker connection with a finger and do not aply to much pressure or it might break. These plugs cost almost twenty dollars at another retailer but comes free with Crunchfield speakers.

Worked Great

Used these in my 2010 Challenger when I replaced my factory speakers. The slip on connectors where a little small for my Rockford Fosgate speakers so I clipped them off and soldered them on to the terminals.

Speaker Wiring Harness (2005 Jeep Wranger - Roll Bar)

I contemplated clipping off the factory connectors and crimping on spade connectors but, I was somewhat concerned about inadvertently reversing the polarity of the speaker wires as well as permanently altering the factory wiring. Then I found this adapter on the Crutchfield website - - I ordered it on a Wednesday night - - it arrived Friday morning! The installation was way too easy - - I installed both speakers in 15 minutes!!

Metra 71-049 Speaker Wiring Adapters

No way, no how, could I get the separate wires to connect to my speaker connecters. I tried to open the harness connecter with a screwdriver only to find out they still won't work.

Crutchfield response on Tuesday, December 04, 2012The plugs on our adapters are smaller than the unusually large terminals on the Boston Acoustics speakers. There are two ways to solve this problem: either splice a small section of the wire supplied with the speakers onto the end of each adapter, or crimp larger plugs onto the adapters.

broken

The adapter fit fine, but one of the spade connectors was missing. I know
Crutchfield would have replaced it, but I had already removed the old speaker
and it was easier to solder the wire to the spade tab on the speaker. Worked
fine from there.

Good fit, broken wire 5 years later

The harness adapter fit well on my Polk db650's in the rear and Polk 6x9's up front. One negative lead on an adapter in the rear broke at the white connector after 5 years of use. This isn't a terrible life span, but disappointing to pull door panels for a broken accessory.

I decided to try Infinity speakers front and rear, so I got 2 more adapters with my latest order. Easy fit on the rear 6.5" Reference speakers. I had to cut off the spade connectors for the 6x9 Kappas screw in connector.

I'll be pleased if I get 5 more years out of my truck and hopefully the new connectors.

Metra 71-049 Speaker Wiring Adapters

The negative (smaller) connector on this wiring adapter did not fit the smaller spade connection on the polk audio 4x6 plate speaker I also purchased from Crutchfield. I had to cut it off and add on my own connector that would fit the spade on the speaker. Not plug and play in my case. Thumbs down guys.

Perfect Fit

Went to 3 electronic stores in town for a speaker harness that would fit my '04 Wrangler. I was told that the manufacturers didn't make them yet and I would have to splice into the wires. One installer even gave me the disconnects, taps and speaker wire, and showed me what to do! I was at my desk ready to start assembly when I remembered Crutchfield. You had the harness I needed. It snapped into place easily and securely and I was done with installation in a matter of minutes.

Features

Crutchfield Speaker Harness: Crutchfield speaker harnesses
prevent you from having to cut your vehicle's factory speaker plugs when
replacing your factory speakers with aftermarket car speakers. The Crutchfield
speaker harness features two female quick-slide connectors on one end to attach
directly to your new aftermarket car speakers & a proprietary Molex connector on
the other end that connects to your vehicle's factory speaker plug.

Quick-Slide Connectors: The Crutchfield speaker harness is equipped with a large (positive) & small
(negative) female quick-slide terminal. These quick-slide terminals fit directly
onto most aftermarket car stereo speaker terminals (slight crimping may be
required). In rare cases that the quick-slide
terminals do not fit your car speaker terminals, you will need to solder the
Crutchfield speaker harness to your aftermarket speaker's terminals or replace
the quick-slide connectors on the Crutchfield speaker harness with the correct
size terminal.

Note: Installation tools, hardware, & accessories are not included
& sold separately. Please see the Accessories tab for recommendations & availability.
